因此，我尝试将我的 ubuntu 版本从 20.04 LTS 更新到 22.04 LTS。但问题是它总是遇到以下错误 -
An unresolvable problem occurred while calculating the upgrade.
This was likely caused by:
* Unofficial software packages not provided by Ubuntu
Please use the tool 'ppa-purge' from the ppa-purge
package to remove software from a Launchpad PPA and
try the upgrade again.
If none of this applies, then please report this bug using the command
'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.
If you want to investigate this yourself the log files in '/var/log/dist-upgrade' will contain details
about the upgrade. Specifically, look at 'main.log' and 'apt.log'.
之前，它说已经禁用了我所有的第三方存储库，所以我相信问题不是来自 PPA，并且我通过取消选中“软件更新和属性”中的所有存储库框来确定这一点。
此后我做了很多寻找，但最终还是没能找到问题的解决方案。
内容主日志文件是：

所以请帮助我将我的 ubuntu LTS 升级到 22.04 版本。
